BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention relates in general to computer programs, and more particularly to a downloading of a computer program.

2. Description of the Related Art

Customers and providers may have a number of requirements in installing or deploying an application program.

Customers may prefer to remotely install application program clients from a central server(s) in order to increase both installation productivity and maintenance productivity. Thin clients may be preferred as thin clients generally require less workstation customization, perhaps as little as a browser with the appropriate option settings and plugins. Preferably, users should be able to move between different workstations, and still be able to access their tools and data, another potential advantage of a thin client. A customer may prefer to control which application programs and which versions of the application programs are available to a particular user. In addition to controlling the application programs, a customer may wish to control access to resources and assets based upon a user's responsibilities and roles in an organization. Alternatively, the customer may wish to control and filter project work views based on the user's responsibilities and roles. In addition to such central control, the customer may want an inventory of the application programs (including versions) installed and used on a workstation or a group of workstations without the need to go to each user workstation.

An application program provider may also have a number of similar requirements in installing or deploying an application program. The provider may also want for licensing purposes the inventory of the application programs (including versions) installed and used on a workstation or a group of workstations without the need to go to each user workstation. To satisfy a customer's specific individual requirements, the provider would prefer a mechanism for configuring the application program to support a customer solution which may be tailored by the customer to suit the customers needs, such as role-based views.

Conventional systems and methods have failed to provide all of the above advantages. Thus, there is a clearly felt need for a method, system, article of manufacture, and computer program product for providing application program downloading with the advantages.

SUMMARY OF THE INVENTION

The present invention comprises a method, system, article of manufacture, and a computer program product for downloading an application program. A configuration of the application program corresponding to a particular user of the local application is defined and stored on a remote server. In response to the user requesting the application program, a session is initiated between the local data processing system and the remote data processing system, and the user is authenticated. Responsive to the user authentication, data is downloaded from the remote server to the local data processing system according to the stored configuration. This stored configuration also may be encrypted and stored in a manifest file which is decrypted to produce a decrypted configuration in response to the user authentication. Data may then be downloaded from the remote data processing system to the local data processing system according to the decrypted configuration. The application program may be constructed pursuant to the configuration file or the decrypted configuration file.

DESCRIPTION OF THE PREFERRED EMBODIMENT

An embodiment of the invention is now described with reference to the figures where like reference numbers indicate identical or functionally similar elements. Also in the figures, the left most digit of each reference number corresponds to the figure in which the reference number is first used. While specific configurations and arrangements are discussed, it should be understood that this is done for illustrative purposes only. A person skilled in the relevant art will recognize that other configurations and arrangements can be used without departing from the spirit and scope of the invention. It will be apparent to a person skilled in the relevant art that this invention can also be employed in a variety of other devices and applications.

With reference now to the figures, and in particular with reference toFIG. 1, there is depicted a pictorial representation of adistributed computer system8 which may be utilized to implement the method of, system for, article of manufacture, and computer program product of the present invention. As may be seen,distributed computer system8 may include a plurality ofnetworks10 and32, which may be Local Area Networks (LAN), intranet networks, or internet networks, each of which preferably includes a plurality ofindividual computers12 and30, respectively. Of course, those skilled in the art will appreciate that a plurality of Intelligent Work Stations (IWS) coupled to a host processor may be utilized for each such network.

As is common in such data processing systems, each individual computer may be coupled to astorage device14 and/or a printer/output device16. One or moresuch storage devices14 may be utilized, in accordance with the present invention, to store the various computer programs which may be accessed and executed by a user within the distributedcomputer system8, in accordance with the present invention. In a manner well known in the prior art, each such computer program may be stored within astorage device14.

Still referring toFIG. 1, it may be seen that distributedcomputer system8 may also include multiple mainframe computers, such asmainframe computer18, which may be preferably coupled toLocal Area Network10 by means ofcommunication link22.Mainframe computer18 may also be coupled to astorage device20 which may serve as remote storage forLocal Area Network10 which may be coupled viacommunications controller26 and communications link34 to agateway server28.Gateway server28 is preferably an individual computer or Intelligent Work Station which serves to linkLocal Area Network32 toLocal Area Network10.

As discussed above with respect toLocal Area Network32 andLocal Area Network10, a plurality of server computer programs may be stored withinstorage device20 and executed bymainframe computer18. Similarly, a plurality of client computer programs may be stored withinstorage devices14 and executed byindividual computers12 such that distributed client/server computer programs are provided. Of course, those skilled in the art will appreciate that themainframe computer18 may be located a great geographical distance fromLocal Area Network10, and similarly,Local Area Network10 may be located a substantial distance fromLocal Area Network32. That is,Local Area Network32 may be located in California whileLocal Area Network10 may be located within Texas andmainframe computer18 may be located in New York.

As will be appreciated upon reference to the foregoing, it is desirable for a user of aworkstation12 to be able to remotely install an application program fromserver18. A configuration of the application program corresponding to this particular user of the application program is defined and stored on aremote storage20 of theremote server18. In response to a user request communicated from theuser workstation12 to theserver18 viaLAN10 and communications link22, theserver18 determines that the configuration stored onstorage20 corresponds to the requesting user.Server18 authenticates the user, and after such authentication, data is downloaded to theworkstation12 from theremote server18 according to the stored configuration. This stored configuration is also encrypted and stored in a manifest file which is also downloaded. Responsive to the user authentication, the manifest file is decrypted, and the application program is constructed, configured, and installed onworkstation12 pursuant to the configuration decrypted from the manifest file. The user may also move from afirst workstation12 on which the application program is installed to a differentsecond workstation12 onLAN10 and still be able to access the user's tools and data which may be downloaded and installed on thesecond workstation12 in a similar fashion to the download and installation on thefirst workstation12. Using the user configurations and authentications stored onstorage20 and theserver18, a customer may control the application programs, the versions of these application programs, and resources that are available to the particular user.

The customer may also inventory the application programs (including versions) installed and used on aworkstation12 or a group ofworkstations12 onLAN10 without the need to go to each user workstation. An application program provider may also want for licensing purposes such an inventory which may be produced by customer'sserver18 or the provider'sserver26.

Referring now toFIG. 2, a block diagram of a preferred embodiment of the present invention is illustrated. A file known as a manifest file ormanifest244 provides a description as to which plugins, configurations, and other resources should be loaded when an application program, such as an Integrated Development Environment (IDE), is initialized. Although the preferred embodiment is presented in the context of an IDE, those skilled in the art will recognize that the invention may be practiced with other types of application programs. The preferred embodiment uses this manifest to provide a mechanism for plugging in tools or components to provide a customized application program with the appropriate viewers, editors, browsers, and other resources to support the user's needs. For example, a customized IDE may be provided with the appropriate viewers, editors, and browsers to support a specific developer's needs. Furthermore, the preferred embodiment allows remote customization and configuration of the application program for an individual user based on the user's role and responsibility in an organization.

The preferred embodiment of the present invention comprises anapplication server202, which may be behind a web server, that is used to defineusers204,206, and208 in a user table210 and to define the users' application program configurations (214,216, and218) in a user IDE configuration table220. This configuration may includeplugins222 to be downloaded, user authorizations for eachuser224, templates for builds226 (pre packaged site JCL), location/configuration ofsite servers228,other information230 such as the location and configuration of system input/output (I/O), and any sitespecific documentation232 which may be shown in a browser or plugin.

Asecurity system234, such as a certificate or simple a logon dialog, may be used by a user to initiate asession236 with the server262. Upon authentication of the user by thesecurity system234, a table lookup of the user table210 is performed andplugins222,authorizations224,templates226,server information228, anddocumentation232 are aggregated into the user'scomponents238 which are downloaded via thedownload240 to the user'sworkstation242. In addition, amanifest244 is created with this configuration information. Thismanifest244 is encrypted and requires authentication from asecurity system246 on theworkstation242 to be decrypted and used to build248 anapplication program250.

After thedownload240 to the user'sworkstation242, the user through a local logon in thesecurity system246 invokes the decryption and use of the manifest244 to build248 the user'spersonalized application program250. Meanwhile a request may be sent, preferably unknown to the user, to theserver202 to check a component configuration table252 maintained in theapplication server202 to determine if any items have been updated. Alternatively, a request may be sent to theserver202 to record in acomponents inventory254 which tools are being used by the user.

Referring now toFIGS. 3 and 4, theflowcharts300 and400 illustrate the operations preferred in carrying out the preferred embodiment of the present invention. In the flowcharts, the graphical conventions of a diamond for a test or decision and a rectangle for a process or function are used. These conventions are well understood by those skilled in the art, and the flowcharts are sufficient to enable one of ordinary skill to write code in any suitable computer programming language.

After thestart305 of theprocess300, process block310 defines a configuration of the application corresponding to aparticular user206 of the application, such as user2, and process block315 then stores theconfiguration216 on aremote server202 executing on a remotedata processing system18. Alternatively, theconfiguration216 may be stored on localdata processing system242. Thereafter, process block320 may initiate a session between the localdata processing system242 and theapplication server202 on remotedata processing system18 in response to theuser206 requesting the application. Responsive to this user request, process block325 authenticates theuser206, and process block330 then determines that the storedconfiguration216 corresponds to the requestinguser206.Process block335 then downloadsdata240 from the remotedata processing system202 to the localdata processing system242 according to the storedconfiguration216. Alternatively, process block335 may access thedata240 from the localdata processing system242 or from another resource within the distributedcomputer system8 according to the storedconfiguration216. Thereafter, processing continues to decision block450 onFIG. 4. This processing path is illustrated by flowchart connectors A,340 onFIGS. 3 and 445 onFIG. 4.Process block450 encrypts the storedconfiguration216 into amanifest file244 which is then downloaded by process block455 from the remotedata processing system202 to the localdata processing system242. Alternatively, process block450 may encrypt the storedconfiguration216 into amanifest file244 which is then stored on the localdata processing system242. After thedownload240 of themanifest file244 and thecomponents238 to theuser workstation242, theuser206 may request abuild248 of the downloadedcomponents238 pursuant to the configuration in themanifest file244. Responsive to such a user request, the user is authenticated byprocess block460, and if theuser206 is authenticated, then process block465 decrypts themanifest file244. Thereafter, process block470 builds, installs, and configures theapplication program250 pursuant to the configuration decrypted from themanifest file244. The process then ends atprocess block475.

In an alternative embodiment of the present invention, an application program is updated for execution on the data processing system. In this alternative embodiment, process block330 also determines if any items described in the configuration have been updated. If an item has been updated, then process block335 retrieves the updated item, and process block470 builds the application program with the updated item.

In still another alternative embodiment of the present invention, an application program is updated for execution on the data processing system based upon determining if any items described in the decrypted configuration have been updated. In this alternative embodiment, process block465 also determines if any items described in the decrypted configuration have been updated. If an item has been updated, then process block470 retrieves the updated item and builds the application program with the updated item.

Using the foregoing specification, the invention may be implemented using standard programming and/or engineering techniques using computer programming software, firmware, hardware or any combination or sub-combination thereof. Any such resulting program(s), having computer readable program code means, may be embodied within one or more computer usable media such as fixed (hard) drives, disk, diskettes, optical disks, magnetic tape, semiconductor memories such as Read-Only Memory (ROM), Programmable Read-Only Memory (PROM), etc., or any memory or transmitting device, thereby making a computer program product, i.e., an article of manufacture, according to the invention. The article of manufacture containing the computer programming code may be made and/or used by executing the code directly or indirectly from one medium, by copying the code from one medium to another medium, or by transmitting the code over a network. An apparatus for making, using, or selling the invention may be one or more processing systems including, but not limited to, central processing unit (CPU), memory, storage devices, communication links, communication devices, servers, input/output (I/O) devices, or any sub-components or individual parts of one or more processing systems, including software, firmware, hardware or any combination or sub-combination thereof, which embody the invention as set forth in the claims. User input may be received from the keyboard, mouse, pen, voice, touch screen, or any other means by which a human can input data to a computer, including through other programs such as application programs, databases, data sets, or files.

One skilled in the art of computer science will easily be able to combine the software created as described with appropriate general purpose or special purpose computer hardware to create a computer system and/or computer sub-components embodying the invention and to create a computer system and/or computer sub-components for carrying out the method of the invention.
